Theoretically, could you use an 3D grid of these devices to continuously sample the gravitational potential they're experiencing, and build a dead-reckoning navigational system?
For measurements as accurate as this, if you sent out a fleet of these things to map the gravitational potential of the Earth by location, for example, you would find that the potential at a given location was changing all the time, so such a map wouldn't be useful for navigation.

[ 2.4 ms ] story [ 28.6 ms ] threadThis is mindboggling. That timeframe is to one second roughly as a millisecond is to the estimated age of the universe.
Is there a readable version if this somewhere? Was it govt funded?
